tuple_oddnum = list(range(1,100,2))
tuple_len = len(tuple_oddnum)
tuple_sum = 0
for i in range(tuple_len): # 你这里转了这么多程序，，直接range(1, 100, 2)不就好了
    tuple_sum = tuple_sum+tuple_oddnum[i]
print(tuple_sum)

##############完善后的代码

tuple_sum = 0
for i in range(1, 100, 2): # 完善部分
    tuple_sum += i
print(tuple_sum)


# 这次不错
